“…In a study by (Soobhany et al 2015a), a comparison of vermicomposting and composting was made based on the Fig. 4 a Suitable household composting system for Lae city (Sharma and Garg 2019) and b large scale composting methodology along with plausible composting technique considering socio-economic factors and resources available in Lae city recovery of nutrients and it was found that the vermicomposting increased P, K, Mg, and Na and reduced Cr, Cu, Co, Zn, and concentrations in comparison to normal composting, due to the presence of earthworms (Soobhany et al 2015b). In another study by (Soobhany 2018) an attempt to remediate metalliferous soil, data analysis showed that vermicompostextracts were more effective in lowering heavy metal concentrations.…”

Lae City (LC) of Morobe Province is the second-largest city in Papua New Guinea. Due to the abundant natural resources it inherits, the resultant urbanization has led to an influx of the human population. This increase in population as a result of industrialization has led to increased municipal solid waste (MSW) accumulation. To address this exigent issue, which affects the nation’s carbon footprint, it is imperative to review socio-economic and geographic factors to establish a feasible approach for managing MSW efficiently and sustainably. In the quest to achieve the same, the present assessment focuses on the 3 core waste management hierarchy systems to support sustainable development for LC by reviewing existing opportunities and challenges associated with the current MSW management system and the associated policies. The result shows that as a sustainable approach to MSW management of LC, a zero-waste campaign for resource recovery engaging all stakeholders can be implemented since the organic content of MSW generated in LC is as high as 70%. Moreover, the dumping of MSW at the dedicated dumpsite site can be minimized if policies are strengthened and the proposed waste avoidance pathway is implemented strictly. In addition to this, to avoid the contamination of groundwater and recovery of methane, the use of the Fukuoka approach in the existing landfills has been suggested to capture leachate without any huge expenditure.

“…Utilizing industrial waste as feed material for earthworms offers the potential for sustainable waste management, resource recovery, and soil improvement . Organic waste materials go through the gizzard of earthworms during this process, producing vermicast, which is rich in essential plant nutrients and unidentified chemicals that stimulate plant development (Sharma and Garg, 2019). Earthworms feed on organic waste voraciously, and while they only use a small fraction of it for body synthesis, they expel a substantial quantity of it in a partially digested state.…”

The discharge of organic waste from distilleries poses a significant hazard to the environment. The dumping of organic wastes results in offensive odours, soil contamination, the spread of viral infections that are extremely contagious and harm a variety of species, as well as vector transmitted diseases that impact humans. Vermi-bioconversion is an ideal technique for employing worms to convert organic waste into nutrient-rich fertilizer, healthy soil, and remediation of soil from pollution. Distillery effluents have a negative impact on the ecosystem and its constituents. These effluents contain more dangerous compounds, such as chloride, sulphate, and nitrate. A viable method for converting waste into rich organic bio-fertilizers is vermicomposting, utilizing earthworms like Lampito mauritii. The pH, organic carbon, organic matter, and the C:N ratio of the different organic waste combinations all tended to decrease throughout this process, whereas the nitrogen content, accessible phosphorous, and exchangeable potassium all tended to increase as the vermicomposting period went on. Consequently, it can be said that using the vermicomposting procedure to handle distillery effluents is simple. Vermicomposting has been shown to be an alternative approach for recycling and environmentally acceptable waste management. In the present study vermicomposting of distillery effluents with various combinations of buffalo dung by using Lampito mauritii was done. The purpose of this study was to use the environmental friendly technology of vermiconversion to solve the waste disposal issue of biological wastes.

“…The benefits of vermicompost include improving soil fertility and soil health, water holding capacity, soil productivity, soil biodiversity, and crop growth and yield, enhancing soil physical, chemical, and biological properties (Joseph, 2019;Zuhair, 2011). In addition, vermicompost is frequently considered a supplement to fertilizers and it releases the nutrients slowly with a significant reduction in C/N ratio, concurrent with the requirement of plants (Sharma and Garg, 2019). During vermicomposting process, the nutrients locked up in the organic waste are changed to simple and more easily available and absorbable forms such as nitrogen, phosphorus, soluble potassium, calcium and magnesium in worm's gut (Sharma et al, 2017).…”

Environmental degradation is a major threat confronting the world, the vermicompost product one of the best organic manure to be used for enhancing soil, crop and environment. This study aimed to the evaluated effect of earthworm species on the availability of macronutrients in the vermicompost. In this direction, the possibilities of using different growth habitats with 4 different earthworm species in an experiment to produce an organic fertilizer (vermicompost) were studied. In conjunction with those from previous studies Ninety days vermicomposting experiment was conducted in polyethylene boxes contained a pre-composted (mixture of cow manure, market wastes, kitchen wastes, sawdust and bagasse). Each type of the followed vermicomposting habitats; 100% precomposted (PC), 75% PC+ 25% cardboard waste (CB) and 75% PC+25% soil (S) were inoculated with one species of earthworms; Allolobophora longa, Eudrilus eugeniae, Eiseia fetida and Perionyx excavatus. The present study concluded that, A. longa could not survive in PC habitat, while other earthworms produced a high quality vermicompost under the same condition. On the other hand, the PC+S habitat was the best for A. longa, which was suitable for growing of the species. The PC+CB and PC+S vermicompost's of E. fetida and PC+S of A. longa had a lowest pH, EC and C/N ratio. The total NPK content and their available forms were enhanced in the vermicompost's of PC+CB and PC+S for all tested worms as compared with PC and untreated with earthworms (control) respectively. In conclusion, he total NPK content and their available forms were enhanced in the vermicompost's of PC+CB and PC+C for all tested worms in compared with PC vermicompost and control treatment, but E. fetida was the best.
